背景技术
在移动通信系统中，一个小区组(Cell Group，CG)可以配置一个或多个非连续接收组(Discontinuous Reception group，DRX group)，其中，不同DRX group的DRX配置参数可单独配置，例如，DRX onDuration定时器(即drx-ondurationtimer)、DRX非激活定时器(即drx-InactivityTimer)等。上述DRX group可以理解为将小区组内的小区按照某种特征进行划分所形成的小区组合，例如，根据不同的频率范围(Frequency Range，FR)配置将小区组内的小区按照FR进行分组，如图1所示。需要说明的是，将小区组内的小区按照某种特征进行划分所所形成的小区组合并不限于称为DRX group。
为了在DRX配置下进一步节能，引入了基于节能物理下行控制信道(Power Saving Physical Downlink Shared Channel，PS-PDCCH)，即唤醒信号(Wake Up Signal，WUS)的概念。PS-PDCCH的下行控制信息(Downlink Control Information，DCI)2_6中唤醒指示(wake up indication)域用于指示下一个DRX周期的drx-ondurationtimer是否开启；DCI格式2_6中还可以配置辅小区休眠指示(SCell dormancy indication)域，用于指示以辅小区组(SCell group)为单位的休眠行为。然而，在现有技术中，在一个小区组配置有一个或多个DRX group的情况下如何配置PS-PDCCH的指示范围，并没有相关的解决方案。

为了便于理解，以下对本发明实施例涉及的一些内容进行说明：
一、无线资源控制(Radio Resource Control，RRC)连接状态(即connected状态)的非连续接收(Discontinuous Reception，DRX)。
DRX基本模型：
一个典型的DRX周期可以如图2所示。DRX的基本机制是为处于RRC_CONNECTED态的UE配置一个DRX周期(即DRX cycle)。DRX cycle包括持续时间(即On Duration)和睡眠时间(即Opportunity for DRX，如图2中的低电平处)，在On Duration的时间内，用户设备(User Equipment，UE)监听并接收物理下行控制信道(Physical Downlink Shared Channel，PDCCH)(激活期)；在Opportunity for DRX时间内，UE不接收下行信道的数据以节省功耗(睡眠期)。
参数配置：
DRX onDuration定时器(即drx-ondurationtimer)：当配置了DRX功能时，在该drx-ondurationtimer表示对应媒体接入控制(Media Access Control，MAC)在一个DRX周期内处于唤醒状态的时长，对应图2中的onDuration的时长。该drx-ondurationtimer可以根据特定公式计算启动时间点，一旦启动则持续运行直至超时，中途不允许重启。
DRX非激活定时器(即drx-InactivityTimer)：该drx-InactivityTimer表示对应MAC在接收到一个指示新传的PDCCH后还需要监听PDCCH的时长。该drx-InactivityTimer在指示新传(UL或DL)的PDCCH接收结束后的第一个符号启动或重启。当对应MAC收到DRX命令(即DRX Command)或长DRX命令(即Long DRX command)MAC控制单元(Control Element，CE)时，停止该drx-InactivityTimer。当该drx-InactivityTimer超时时，如果对应 MAC配置短DRX周期，则进入短DRX周期，否则进入长DRX周期。
需要说明的是，上述两个Timer以毫秒为单位，例如，可以如下所示：
drx-ondurationtimer CHOICE{subMilliSeconds INTEGER(1..31),milliSeconds ENUMERATED{ms1,ms2,ms3,ms4,ms5,ms6,ms8,ms10,ms20,ms30,ms40,ms50,ms60,ms80,ms100,ms200,ms300,ms400,ms500,ms600,ms800,ms1000,ms1200,ms1600,spare8,spare7,spare6,spare5,spare4,spare3,spare2,spare1}},
drx-InactivityTimer ENUMERATED{ms0,ms1,ms2,ms3,ms4,ms5,ms6,ms8,ms10,ms20,ms30,ms40,ms50,ms60,ms80,ms100,ms200,ms300,ms500,ms750,ms1280,ms1920,ms2560,spare9,spare8,spare7,spare6,spare5,spare4,spare3,spare2,spare1}。
二、节能PDCCH(Power Saving PDCCH，PS-PDCCH)的下行控制信息(Downlink Control Information，DCI)2_6(即PS-PDCCH of DCI 2_6)。
为了在DRX配置下进一步节能，提出了PS-PDCCH，即唤醒信号(Wake Up Signal，WUS)的概念，WUS对应DCI 2_6，并且DCI 2_6只能配置在主小区(Primary Cell，Pcell)上。WUS可控制下一个DRX周期的drx-ondurationtimer是否开启。DCI 2_6存在于激活时间之外(即outside active time)。需要说明的是，只有在配置了连接态的DRX(Connected DRX，CDRX)的情况下，才能配置PS-PDCCH。
可选地，DCI格式2_6(即DCI format 2_6)可以包括两个域，这两个域包括：
唤醒指示域(即wake up indication)(1bit)；
辅小区休眠指示域(即Scell dormancy indication)(0,1,2,3,4,5bits)。
可选地，DCI格式2_6用于在一个或多个UE的DRX激活时间之外通知省电信息。
下列信息通过省电无线网络临时标识(即PS-RNTI)加扰循环冗余校验(CRC)的DCI格式2_6来传输：
块编号1(即block number 1),块编号2(即block number 2),…,块编号N(即block number N)；其中，块的起始位置由较高层为配置有该块的UE提供的节能位置DCI 2_6(即PSPositionDCI 2_6)参数确定。
如果UE配置有较高层参数PS-RNTI和DCI-Format 2_6，则高层将为UE配置一个块，并为该块定义以下字段：
唤醒指示域(即wake up indication)-1比特(即bit)；
辅小区休眠指示域(即SCell dormancy indication)-如果未配置高层参数激活时间之外的辅小区休眠(即Scell-groups-for-dormancy-outside-active-time)，则为0bit；否则根据高层参数Scell-groups-for-dormancy-outside-active-time确定的1、2、3、4或5比特的位图，其中每个比特对应于由高层参数Scell-groups-for-dormancy-outside-active-time配置的一个辅小区(Secondary Cell，SCell)组，其中最高有效位(the Most Significant Bit，MSB)到最低有效位(the Least Significant Bit，LSB)的位图对应于第一个到最后一个配置的SCell组。
PS-PDCCH对应的DCI格式是DCI 2_6，即用PS-RNTI加扰CRC的DCI格式2_6(即the DCI format 2_6with CRC scrambled by PS-RNTI)。其中PS-RNTI是网络侧设备为UE分配的专门用于省电特性的RNTI，以该PS-RNTI加扰的DCI，即携带了网络侧设备对UE的唤醒/睡眠指示。UE根据该指示，决定下一个DRX周期是否启动onDuration定时器(即drx-ondurationtimer)，是否启动该drx-ondurationtimer也就是是否在onduration中监听PDCCH，如图3所示。
在没有配置DRX group前，DRX和PS_PDCCH都是基于终端的每个小区组的配置。
三、PS-PDCCH的检测。
情况一：若UE被提供了搜索空间集(Search Space sets，SS sets)以检测一个或多个DCI format 2_6的PS-PDCCH监听时机(Monitoring Occasion，MO)，并且UE没有检测到DCI format 2_6(PS-PDCCH)，则UE的行为由RRC配置的是否节能唤醒(即ps-WakeupOrNot)参数指示是否启动下一个DRX周期的drx-ondurationtimer，或者在未给UE配置ps-WakeupOrNot的情况下，不开启下一个DRX周期的drx-ondurationtimer。
情况二：若UE被提供了SS sets以检测一个或多个DCI format 2_6的PDCCH MO，在下述两种情况下UE行为是启动下一个DRX周期的drx-ondurationtimer：一、不需要监听全部PDCCH MO；二、没有任何的PDCCH MO。如图4所示。
本发明实施例提供一种PS-PDCCH配置方法。参见图5，图5是本发明实施例可应用的一种网络系统的结构图，如图5所示，包括终端设备11和网络侧设备12，其中，终端设备11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等用户侧设备，需要说明的是，在本发明实施例中并不限定终端设备11的具体类型。网络侧设备12可以是基站，例如：宏站、LTE eNB、5G NR NB、gNB等；网络侧设备12也可以是小站，如低功率节点(Low Power Node，LPN)pico、femto等小站，或者网络侧设备12可以是接入点(Access Point，AP)；基站也可以是中央单元(Central Unit，CU)与其管理是和控制的多个TRP共同组成的网络节点。需要说明的是，在本发明实施例中并不限定网络侧设备12的具体类型。
本发明实施例提供一种PS-PDCCH配置方法，应用于终端设备。参见图6，图6是本发明实施例提供的一种PS-PDCCH配置方法的流程图，如图6所示，包括以下步骤：
步骤601、获取第一配置参数；其中，所述第一配置参数用于指示PS-PDCCH支持指示的对象，所述对象包括N个DRX group和M个小区中的至少一项，N和M均为正整数。
本实施例中，上述第一配置参数可以由协议预定义，也可以由网络侧设 备配置。其中，上述第一配置参数可以用于指示一个小区组内配置的PS-PDCCH指示该小区组内的M个小区和N个DRX group中的至少一项，上述M个小区可以包括该小区组内的部分小区或是全部小区，上述N个DRX group也可以包括该小区组内配置的部分DRX group或者全部DRX group。
例如，可以协议预定义或者由网络侧设备配置一个小区组中配置的PS-PDCCH支持指示该小区组内配置的全部DRX group或全部小区；或者协议预定义或者由网络侧设备配置一个小区组中配置的PS-PDCCH支持指示该小区组内配置的主DRX group(即Primary DRX group)或主小区(Primary Cell，PCell)，其中，主DRX group可以是指Pcell所在的DRX group；或者协议预定义或者由网络侧设备配置一个小区组中配置的PS-PDCCH支持指示该小区组内配置的辅DRX group(即Secondary DRX group)或辅小区(Secondary Cell，SCell)，其中，辅DRX group可以是指不包括PCell的一个或多个DRX group。
需要说明的是，上述PS-PDCCH指示小区或者DRX group，可以理解为在该PS-PDCCH的DCI(如DCI格式2_6)中配置有唤醒指示域的情况下，通过唤醒指示域指示该小区或者DRX group位于该唤醒指示域之后的DRX周期的drx-ondurationtimer是否开启；在该PS-PDCCH的DCI中配置有辅小区休眠指示域的情况下，通过该辅小区休眠指示域指示是否休眠该小区所在的辅小区组或者该DRX group对应小区所形成的辅小区组。
可选地，本实施例可以在一个小区组内配置有一个或多个DRX group的情况下，获取用于指示该小区组内配置的PS-PDCCH支持指示的对象的第一配置参数。
可选地，本实施例在PS-PDCCH支持指示的对象包括DRX group的情况下，可以是在一个小区组内配置有多个DRX group的情况下，获取用于指示该小区组内配置的PS-PDCCH支持指示的对象的第一配置参数；在PS-PDCCH支持指示的对象仅包括小区的情况下，可以是在一个小区组内配置有一个或多个DRX group的情况下，获取用于指示该小区组内配置的PS-PDCCH支持指示的对象的第一配置参数。
具体地，终端设备在获取第一配置参数之后，可以接收PS-PDCCH，并 基于所接收的PS-PDCCH指示所述N个DRX组和M个小区中的至少一项。需要说明的是，对于小区组中除N个DRX组之外的DRX组或除M个小区之外小区可以遵循未配置PS-PDCCH时的处理行为。
本发明实施例提供的PS-PDCCH配置方法，通过第一配置参数指示PS-PDCCH支持指示的N个DRX group和M个小区中的至少一项，提供了一种在一个小区组配置有一个或多个DRX group的情况下配置PS-PDCCH的指示范围的方式，进而可以提高基于PS-PDCCH指示DRX group和小区中的至少一项的灵活性。
可选地，N的取值范围可以为[1，K]，K为在所述PS-PDCCH对应的小区组中配置的DRX group个数；
和/或
M的取值范围可以为[1，L]，L为在所述PS-PDCCH对应的小区组中配置的小区个数。
上述PS-PDCCH对应的小区组也即配置了该PS-PDCCH的小区组。
本实施例中，由于可以配置一个小区组中配置的PS-PDCCH支持指示该小区组内任意数量的小区，或者可指示该小区组内配置的任意数量的DRX group，或者可指示该小区组内任意数量的小区和任意数量的DRX group，因此基于PS-PDCCH进行指示的灵活性较高，进而可以达到省电的目的。
可选地，所述第一配置参数可以包括如下至少一项：
所述N个DRX group中每个DRX group的标识；
所述M个小区中每个小区的标识；
所述N个DRX group或者所述M个小区对应的小区组的标识。
本实施例中，上述第一配置参数可以包括PS-PDCCH支持指示的小区的标识、DRX group的标识、支持的小区或DRX group对应的小区组的标识中的至少一项。例如，上述第一配置参数可以包括DRX group ID列表和/或Cell ID列表，上述DRX group ID列表包括N个DRX group ID，上述Cell ID列表包括M个Cell ID。
可选地，在PS-PDCCH支持指示小区组内的全部小区的情况下，上述第一配置参数可以仅包括小区组的标识。
需要说明的是，一个小区组内的小区的ID或一个小区组内配置的DRX group的ID可以根据实际情况进行合理设置。例如，小区组中对应的小区包括Pcell的DRX group的ID可以为0，Pcell的ID可以为0，并可以按照ID递增的顺序依次设置该小区组中其他的DRX group的ID和/或其他小区的ID。
本实施例中通过第一配置参数显示指示PS-PDCCH支持指示的小区、DRX group和支持的小区或DRX group对应的小区组的标识中的至少一项，便于终端设备快速确定PS-PDCCH支持指示的小区和DRX group中的至少一项。
可选地，所述对象包括N个DRX group和M个小区，且所述M个小区所在的DRX group包含于所述N个DRX group。
本实施例中，在配置PS-PDCCH支持指示N个DRX group和M个小区的情况下，终端设备可以期望M个小区所在的DRX group包含于N个DRX group，这样可以避免在通过PS-PDCCH指示N个DRX group和M个小区的情况下出现冲突。
可选地，在PS-PDCCH支持指示N个DRX group和M个小区的情况下，所述PS-PDCCH可以配置为指示N个DRX group对应的小区和M个小区之间的交集，以避免出现冲突。
可选地，在所述对象包括N个DRX group和M个小区的情况下，所述PS-PDCCH配置为指示所述N个DRX group或者所述M个小区。
本实施例中，在配置PS-PDCCH支持指示N个DRX group和M个小区的情况下，为避免冲突，PS-PDCCH在具体指示过程中可以仅指示N个DRX group或者M个小区，也即在PS-PDCCH的具体指示过程中仅以DRX group和Cell中的一种粒度进行指示。
可选地，在所述PS-PDCCH的下行控制信息DCI中配置有唤醒指示域的情况下，所述N个DRX group或者所述M个小区均通过所述唤醒指示域的相同比特位指示；
或者
在所述PS-PDCCH的DCI中配置有唤醒指示域的情况下，所述N个DRX group中的不同DRX group或者所述M个小区中的不同小区分别通过所述唤 醒指示域的不同比特位指示。
在一实施方式中，在PS-PDCCH的DCI中配置有唤醒指示(即wake up indication)域的情况下，可以通过唤醒指示域的相同比特位指示是否启动所述N个DRX group或者所述M个小区的下一个DRX周期的drx-ondurationtimer。也即不同的DRX group或不同的Cell通过唤醒指示域的相同比特位进行指示(即联合指示)，这种指示方式实现较为简单。
例如，所述N个DRX group或者所述M个小区均通过唤醒指示域的同一个比特位指示，或者所述N个DRX group或者所述M个小区均通过唤醒指示域中相同的多个比特位(例如，2个比特位)指示，如所述N个DRX group或者所述M个小区均通过唤醒指示域中的第一个比特位和第二个比特位共同指示。
在另一实施方式中，在PS-PDCCH的DCI中配置有唤醒指示域的情况下，可以通过唤醒指示域的不同比特位指示分别指示是否启动所述N个DRX group中的不同DRX group的下一个DRX周期的drx-ondurationtimer或者所述M个小区中的不同小区的下一个DRX周期的drx-ondurationtimer。也即不同的DRX group或不同的Cell通过唤醒指示域的不同比特位进行指示(即独立指示)，这种指示方式较为灵活。
具体地，若配置唤醒指示域独立指示N个DRX group中每个DRX group或M个Cell中每个Cell，则可以为每一个DRX group或每个Cell配置对应1个wake up indication比特，N个DRX group或M个cell分别遵循各自的wake up indication比特的指示。
可选地，在所述N个DRX group中的不同DRX group或者所述M个小区中的不同小区分别通过所述唤醒指示域的不同比特位指示的情况下，所述PS-PDCCH的DCI中未配置辅小区休眠指示域。
本实施例中，在所述N个DRX group中的不同DRX group或者所述M个小区中的不同小区分别通过所述唤醒指示域的不同比特位指示的情况下，终端设备可以期望PS-PDCCH的DCI中未配置辅小区休眠指示(即Scell dormancy indication)域，以节省资源开销。
可选地，在所述PS-PDCCH的DCI中配置有辅小区休眠指示域的情况 下，辅小区组SCell group按照第一分组方式或者第二分组方式得到；
其中，所述第一分组方式为在所述N个DRX group的每个DRX group中进行Scell分组形成SCell group；所述第二分组方式为所述N个DRX group中的SCell统一分组形成SCell group。
在一实施方式中，在所述PS-PDCCH的DCI中配置有辅小区休眠指示域的情况下，可以分别在所述N个DRX group的每个DRX group中进行Scell分组形成SCell group，也即每个SCell group中的SCell来自同一个DRX group。这样可以避免由于跨DRX group进行SCell分组引起的一个SCell group内存在不同DRX相关timer配置，造成监听PDCCH起止时间不同步等问题。此外，由于一个DRX group中SCell的FR相同，更适合放到一个SCell group进行统一的指示。例如，一个小区组中配置的PS-PDCCH支持指示该小区组中配置的DRX group1和DRX group2，则可以将DRX group1对应的Scell进行分组形成SCell group，将DRX group2对应的Scell进行分组形成SCell group。
在另一实施方式中，在所述PS-PDCCH的DCI中配置有辅小区休眠指示域的情况下，可以将所述N个DRX group中的SCell统一分组形成SCell group，也即一个SCell group中的SCell可以来自不同的DRX group对应的SCell。这样可以减少由于引入多个DRX group带来的协议改动。例如，一个小区组中配置的PS-PDCCH支持指示该小区组中配置的DRX group1和DRX group2，则可以将DRX group1对应的Scell和DRX group2对应的Scell进行统一分组形成SCell group。
需要说明的是，对于所形成的不同的SCell group，可以通过辅小区休眠指示域的不同指示位进行指示。
可选地，在所述PS-PDCCH的DCI中配置有唤醒指示域和辅小区休眠指示域，且所述N个DRX group中的不同DRX group分别通过所述唤醒指示域的不同比特位指示的情况下，Scell group按照第三分组方式分组得到；
其中，所述第三分组方式为在所述N个DRX group的每个DRX group中进行Scell分组形成SCell group。
本实施例中，在所述PS-PDCCH的DCI中同时配置有唤醒指示域和辅小 区休眠指示域的情况下，若所述N个DRX group中的不同DRX group分别通过所述唤醒指示域的不同比特位指示，则在所述N个DRX group的每个DRX group中进行Scell分组形成SCell group，也即只能在DRX group内形成SCell group，每个SCell group中的SCell来自同一个DRX group，这样做可以避免由于不同DRX group的唤醒指示域指示不一致时，一个SCell group内SCell的休眠行为不同的问题。否则，可以在所述N个DRX group的每个DRX group中进行Scell分组形成SCell group，也可以将所述N个DRX group中的SCell统一分组形成SCell group。
可选地，若所述PS-PDCCH的DCI未配置唤醒指示域但配置了辅小区休眠指示域，则可以开启N个DRX group或M个Cell的每个DRX周期的drx-ondurationtimer，并可根据辅小区休眠指示域中对于每个SCell group的指示来分别进行休眠或非休眠行为。
可选地，若所述PS-PDCCH的DCI配置了唤醒指示域和辅小区休眠指示域，则可以根据所述唤醒指示域的指示来判断是否开启下一个DRX周期的drx-ondurationtimer，其中，所述辅小区休眠指示域只对所述唤醒指示域指示开启drx-ondurationtimer的DRX group中的SCell group有效。
可选地，所述第一配置参数还包括第一指示参数，所述第一指示参数用于指示所述终端设备执行第一处理行为，所述第一处理行为包括如下之一：
开启所述N个DRX group中每个DRX group的下一个DRX周期的DRX持续时间定时器drx-ondurationtimer；
根据所述PS-PDCCH的指示确定是否开启所述N个DRX group中每个DRX group的下一个DRX周期的drx-ondurationtimer；
根据所述PS-PDCCH针对第一DRX group的指示确定是否开启所述第一DRX group的下一个DRX周期的drx-ondurationtimer，且开启第二DRX group的下一个DRX周期的drx-ondurationtimer；
开启第一DRX group的下一个DRX周期的drx-ondurationtimer，且根据所述PS-PDCCH针对第二DRX group的指示确定是否开启所述第二DRX group的下一个DRX周期的drx-ondurationtimer；
开启第三DRX group的下一个DRX周期的drx-ondurationtimer，且根据 所述PS-PDCCH针对第四DRX group的指示确定是否开启所述第四DRX group的下一个DRX周期的drx-ondurationtimer；
其中，所述第一DRX group为所述N个DRX group中主小区Pcell所在的DRX group；所述第二DRX group为所述N个DRX group中除所述第一DRX group之外的DRX group；所述第三DRX group为所述N个DRX group中DRX非激活定时器drx-inactivitytimer的运行时间覆盖了所述PS-PDCCH监听时机MO的DRX group；所述第四DRX group为所述N个DRX group中除所述第三DRX group之外的DRX group。
可选地，所述第一指示参数用于指示所述终端设备在第一情况或者第二情况下执行所述第一处理行为；
其中，所述第一情况为第一小区所在的DRX group的drx-inactivitytimer的运行时间覆盖所述PS-PDCCH MO，所述第一小区为所述PS-PDCCH对应的小区组中的任一辅小区SCell；
所述第二情况为第二小区所在的DRX group的drx-inactivitytimer的运行时间覆盖所述PS-PDCCH MO，所述第二小区为所述PS-PDCCH对应的小区组中的主小区。
本实施例中，在第一小区(也即非Pcell)所在的DRX group的drx-inactivitytimer的运行时间覆盖所述PS-PDCCH MO的情况下，如图7所示，或者在第二小区(也即Pcell)所在的DRX group的drx-inactivitytimer的运行时间覆盖所述PS-PDCCH MO的情况下，如图8所示，终端设备可以执行如下任一种处理行为：
处理行为一，开启所述N个DRX group中每个DRX group的下一个DRX周期的drx-ondurationtimer，以减少数据传输的时延。
处理行为二，仍然根据所述PS-PDCCH的指示确定是否开启所述N个DRX group中每个DRX group的下一个DRX周期的drx-ondurationtimer，以在减少数据传输的时延的同时节省电量。
处理行为三，根据所述PS-PDCCH针对第一DRX group的指示确定是否开启所述第一DRX group的下一个DRX周期的drx-ondurationtimer，且开启第二DRX group的下一个DRX周期的drx-ondurationtimer，这样可以在节省 Pcell数据传输电量的同时，减少SCell数据传输的时延。
处理行为四，开启第一DRX group的下一个DRX周期的drx-ondurationtimer，且根据所述PS-PDCCH针对第二DRX group的指示确定是否开启所述第二DRX group的下一个DRX周期的drx-ondurationtimer，这样可以在节省Scell数据传输电量的同时，减少PCell数据传输的时延。
处理行为五，开启第三DRX group的下一个DRX周期的drx-ondurationtimer，且根据所述PS-PDCCH针对第四DRX group的指示确定是否开启所述第四DRX group的下一个DRX周期的drx-ondurationtimer，这样可以在减少覆盖了PS-PDCCH MO的DRX group对应的小区的数据传输的时延的同时，减少其他DRX group对应的小区的数据传输的电量。
可选地，在Pcell所在的DRX group上的inactivitytimer的运行时间覆盖了所述PS-PDCCH MO的情况下，终端设备也可以开启所述N个DRX group中每个DRX group的下一个DRX周期的drx-ondurationtimer，以减少数据传输的时延。
需要说明的是，上述PS-PDCCH可以配置在小区组的PCell上。
可选地，所述获取第一配置参数，可以包括如下一项：

根据接收的下行控制信息DCI信令或者媒体接入控制控制单元MAC CE，从I组配置参数中确定第一配置参数；I为大于1的整数；
根据接收的DCI信令，从J组配置参数中确定第一配置参数；其中，所述J组配置参数是通过RRC信令配置、且通过媒体接入控制控制单元MAC CE激活的，J为大于1的整数。
在一实施方式中，网络侧设备可以通过RRC信令仅为终端设备配置一组配置参数，也即第一配置参数，这样终端设备可以通过RRC信令从网络侧设备接收第一配置参数，并基于第一配置参数可以获知PS-PDCCH支持指示的N个DRX group和M个小区中的至少一项。这种参数配置方式实现较为简便。
在另一实施方式中，网络侧设备可以通过RRC信令为终端设备配置I组配置参数，并通过DCI信令或者MAC CE激活I组配置参数中的一组配置参 数。这样终端设备可以基于DCI信令或者MAC CE激活的一组配置参数(也即第一配置参数)获知PS-PDCCH支持指示的N个DRX group和M个小区中的至少一项。这种参数配置方式较为灵活，进而可以提高PS-PDCCH指示的灵活性。
在另一实施方式中，网络侧设备可以通过RRC信令为终端设备配置I组配置参数，并通过MAC CE激活I组配置参数中的J组配置参数，在基于DCI信令指示激活的J组配置参数中的一组配置参数，该DCI可以是DCI格式2_6或调度DCI格式1_1或0_1等。这样终端设备可以基于DCI信令指示的一组配置参数(也即第一配置参数)获知PS-PDCCH支持指示的N个DRX group和M个小区中的至少一项。这种参数配置方式较为灵活，进而可以提高PS-PDCCH指示的灵活性。

可选地，本实施例在PS-PDCCH支持指示的对象包括DRX group的情况下，可以是在一个小区组内配置有多个DRX group的情况下，获取用于指示该小区组内配置的PS-PDCCH支持指示的对象的第一配置参数；在PS-PDCCH支持指示的对象仅包括小区的情况下，可以是在一个小区组内配置有一个或多个DRX group的情况下，获取用于指示该小区组内配置的PS-PDCCH支持指示的对象的第一配置参数。
本发明实施例提供的PS-PDCCH配置方法，通过向终端设备发送第一配置参数以指示PS-PDCCH支持指示的N个DRX group和M个小区中的至少一项，提供了一种在一个小区组配置有一个或多个DRX group的情况下配置PS-PDCCH的指示范围的方式，进而可以提高基于PS-PDCCH指示DRX group和小区中的至少一项的灵活性。

在另一实施方式中，在PS-PDCCH的DCI中配置有唤醒指示域的情况下，可以通过唤醒指示域的不同比特位指示分别指示是否启动所述N个DRX group中的不同DRX group的下一个DRX周期的drx-ondurationtimer或者所述M个小区中的不同小区的下一个DRX周期的drx-ondurationtimer。也即不同的DRX group或不同的Cell通过唤醒指示域的不同比特位进行指示(即独立指示)，这种指示方式较为灵活。
可选地，在所述N个DRX group中的不同DRX group或者所述M个小区中的不同小区分别通过所述唤醒指示域的不同比特位指示的情况下，所述PS-PDCCH的DCI中未配置辅小区休眠指示域。
本实施例中，在所述N个DRX group中的不同DRX group或者所述M个小区中的不同小区分别通过所述唤醒指示域的不同比特位指示的情况下，网络侧设备可以不在PS-PDCCH的DCI中配置辅小区休眠指示域，以节省资源开销。

本实施例中，在所述PS-PDCCH的DCI中同时配置有唤醒指示域和辅小区休眠指示域的情况下，若所述N个DRX group中的不同DRX group分别通过所述唤醒指示域的不同比特位指示，则在所述N个DRX group的每个DRX group中进行Scell分组形成SCell group，也即只能在DRX group内形成SCell group，每个SCell group中的SCell来自同一个DRX group对应的SCell；否则，可以在所述N个DRX group的每个DRX group中进行Scell分组形成SCell group，也可以将所述N个DRX group中的SCell统一分组形成SCell group。
可选地，所述第一配置参数还包括第一指示参数，所述第一指示参数用于指示所述终端设备执行第一处理行为，所述第一处理行为包括如下之一：

通过RRC信令向所述终端设备发送第一配置参数。
本实施方式中，网络侧设备可以通过RRC信令仅为终端设备配置一组配置参数，也即第一配置参数，这样终端设备可以通过RRC信令从网络侧设备接收第一配置参数，并基于第一配置参数可以获知PS-PDCCH支持指示的N个DRX group和M个小区中的至少一项。这种参数配置方式实现较为简便。
可选地，所述向终端设备发送第一配置参数，包括：

在一实施方式中，网络侧设备可以通过RRC信令为终端设备配置I组配置参数，并通过DCI信令或者MAC CE激活I组配置参数中的一组配置参数。这样终端设备可以基于DCI信令或者MAC CE激活的一组配置参数(也即第一配置参数)获知PS-PDCCH支持指示的N个DRX group和M个小区中的至少一项。这种参数配置方式较为灵活，进而可以提高PS-PDCCH指示的灵活性。

以下结合举例对本发明实施例进行说明：
示例一：一个PS-PDCCH仅指示辅DRX group(即Scondary DRX group)，且采用联合指示所有DRX group的方式。
例如，如图10和图11所示，网络侧设备通过RRC配置一个小区组中有3个DRX group，并在Pcell上配置一个PS-PDCCH进行联合DRX group指示且PS-PDCCH对应的DCI 2_6中配置了唤醒指示(wake up indication)域和辅小区休眠指示(Scell dormancy indication)域。按照不同的DRX group将辅小区(Scell)分组，每一组Scell再细分为不同的辅小区组(Scell group)，在本示例中，DRX group1形成辅小区组1，DRX group1形成辅小区组2。
UE通过接收RRC高层信令参数直接获得DRX group ID列表(也即上述的第一配置参数)为{1,2}，也即PS-PDCCH作用于DRX group1和DRX group2，其中PS-PDCCH1中的wake-up indication指示DRX group1和DRX group2的第一个DRX周期的drx-ondurationtimer关闭，PS-PDCCH2中的wake-up indication指示DRX group1和DRX group2的第二个DRX周期的drx-ondurationtimer为开启。且根据配置的SCell group，PS-PDCCH1中的SCell dormancy indication1在drx-ondurationtimer不开启时指示不生效，PS-PDCCH2 中的SCell dormancy indication2的指示在drx-ondurationtimer开启时生效。
示例二：一个PS-PDCCH指示全部的DRX group，且采用独立指示DRX group的方式。
例如，如图12和图13所示，网络侧设备通过RRC配置一个小区组中有3个DRX group，并在Pcell上配置一个PS-PDCCH进行独立DRX group指示且PS-PDCCH对应的DCI 2_6中配置了wake up indication域。RRC配置所有可能的配置参数组合分别为：{}、{0}，{1}，{2}，{0,1}、{0,2}、{1,2}、{0,1,2}，MAC CE激活其中的{0,1}、{0,2}、{1,2}、{0,1,2}，DCI中用不超过2比特动态的来指示某一种配置参数，例如，DCI中DRX group配置于中指示“11”，即表示{0,1,2}配置被激活。
UE获得当前PS-PDCCH可独立指示的DRX group为DRX group0，DRX group1和DRX group2，其中PS-PDCCH1中的wake-up indication指示DRX group0的第一个DRX周期的drx-ondurationtimer开启，指示DRX group1的第一个DRX周期的drx-ondurationtimer开启，指示DRX group2的第一个DRX周期的drx-ondurationtimer关闭。PS-PDCCH2中的wake-up indication指示DRX group0的第二个DRX周期的drx-ondurationtimer关闭，指示DRX group1的第二个DRX周期的drx-ondurationtimer关闭，指示DRX group2的第二个DRX周期的drx-ondurationtimer开启。
示例三：一个PS-PDCCH指示部分cell，且采用独立指示每个cell的方式。
例如，如图14和图15所示，网络侧设备通过RRC配置一个小区组中有6个小区，以及3个DRX group，并在Pcell上配置一个PS-PDCCH进行独立cell指示且PS-PDCCH对应的DCI 2_6中配置了wake up indication域。
UE通过接收RRC高层信令参数直接获得cell ID列表{2,3,4,5}，也即当前PS-PDCCH独立作用于cell2、cell3、cell4和cell5。其中PS-PDCCH1中的wake-up indication指示cell2、cell3、cell4和cell5的第一个DRX周期的drx-ondurationtimer分别为开启、关闭、开启、关闭。PS-PDCCH2中的wake-up indication指示cell2、cell3、cell4和cell5的第二个DRX周期的drx-ondurationtimer分别为关闭、关闭、关闭、开启。
示例四：一个PS-PDCCH指示部分DRX group的部分cell，且采用独立指示DRX group的方式。
例如，如图16和图17所示，网络侧设备通过RRC配置一个小区组中有6个小区，以及3个DRX group，并在Pcell上配置一个PS-PDCCH进行独立DRX group指示且PS-PDCCH对应的DCI 2_6中配置了wake up indication域。
UE通过接收RRC高层信令参数直接获得DRX group ID和cell ID列表分别为{1,2}和{2,4}。UE获得当前PS-PDCCH独立作用于DRX group1中的cell 2和DRX group2中的cell4。其中PS-PDCCH1中的wake-up indication指示DRX group1的第一个DRX周期的drx-ondurationtimer开启，指示DRX group2的第一个DRX周期的drx-ondurationtimer关闭。PS-PDCCH2中的wake-up indication指示DRX group1的第二个DRX周期的drx-ondurationtimer关闭，指示DRX group2的第二个DRX周期的drx-ondurationtimer开启。
